Roth IRA vs. Traditional IRA — Which Is Right for You?

The One Core Difference

Both accounts invest in the same things — stocks, bonds, index funds. The only difference is when you pay taxes.

*Traditional IRA deductibility phases out at higher incomes if you also have a workplace retirement plan.

The Simple Decision Framework

Ask yourself one question: Will your tax rate be higher now or in retirement?

• Higher now → Traditional (defer taxes until you're in a lower bracket)
• Higher in retirement → Roth (pay taxes now at the lower rate)
• Not sure → Roth (tax-free growth is hard to beat, and young earners are almost always in a lower bracket today than they will be later)

For most people early in their careers

Your income is lower now than it will likely be in 5–10 years. Paying tax now (Roth) at your current 22% or 24% bracket is almost certainly better than paying at whatever rate applies in retirement after 30 years of career growth.

For peak earners (35%+ marginal bracket)

The immediate tax deduction from a traditional IRA (or traditional 401k) has real value. Deferring $7,000 in a 37% bracket saves $2,590 in taxes today. If you expect to be in a lower bracket in retirement, traditional wins.

The Tax-Free Growth Argument for Roth

There's an underappreciated advantage to the Roth beyond just the withdrawal tax rate: all growth is tax-free, forever.

A traditional IRA that grows from $7,000 to $70,000 — you owe taxes on the full $70,000 when you withdraw. A Roth IRA that grows from $7,000 to $70,000 — you owe nothing. Over decades of compounding, this difference is significant.

Income Limits

Roth IRA contributions phase out at higher incomes:

2025 limits. Adjusted annually for inflation.

If you earn too much for a direct Roth contribution, you can use the backdoor Roth strategy: make a non-deductible traditional IRA contribution and immediately convert it to Roth. This is legal and widely used.

Traditional IRA contributions have no income limits, but the deductibility phases out if you have a workplace plan and earn above certain thresholds.

The Flexibility Advantage of Roth

Roth IRAs have one feature traditional IRAs don't: you can withdraw your contributions (not earnings) at any time, penalty-free and tax-free.

This makes a Roth IRA a reasonable place to keep money you might need in an emergency if you've already maxed your emergency fund — though it's better to leave it invested.

Traditional IRAs have no such flexibility — any early withdrawal before age 59½ is hit with a 10% penalty plus income taxes.

Can You Have Both?

Yes. You can contribute to both a Roth and a traditional IRA in the same year, as long as your total contributions don't exceed the annual limit ($7,000 in 2025). Having both gives you tax diversification — flexibility in retirement to withdraw from whichever account is most advantageous in a given tax situation.

What About a Roth 401(k)?

Many employers now offer a Roth 401(k) option alongside a traditional 401(k). Same tax logic applies — Roth 401(k) contributions are after-tax, withdrawals are tax-free. Unlike a Roth IRA, there are no income limits for Roth 401(k) contributions.

High earners above the Roth IRA income limit can still use the Roth 401(k).

FAQ

Should I convert my traditional IRA to a Roth?

A Roth conversion means paying taxes now on the converted amount. It makes sense in years where your income (and thus tax rate) is temporarily low — a gap year, early retirement, or a year with large deductions. It generally doesn't make sense to convert in a high-income year.

Is a Roth IRA better than a 401(k)?

They serve different purposes and you should ideally use both. See: IRA vs. 401(k) — What's the Difference?

What happens to my Roth IRA when I die?

Inherited Roth IRAs are generally still tax-free for beneficiaries. This makes a Roth an efficient estate planning tool — you leave tax-free money to heirs rather than a tax liability.
